SmartFit 3D

What Problems Can It Solve?• Best-fit a part to its tolerance zones• Assess profile tolerances on complex surfaces• Find the best coordinate systems for machining• Determine the best achievable tolerance• Find set-up problems and determine new, better datum targets• Troubleshoot the manufacturing process using intelligent “what if” analysis• Analyze assemblies and provide advice on correction

Two Distinct Working ModesData imported into SmartFit 3D can be optimized in “Point to Point” or “Point to Surface” mode.

In “Point to Point” mode, the nominal coordinates of each measured point are explicitly defined, and remain unchanged during the entire optimization process.

“Point to Surface” mode represents the nominal part with a CAD model, while the nominal points are represented by the projected coordinates, which usually vary at each optimization step.

High Performance 2D/3D Fitting & Analysis Software

SmartFit 3D displays tabular data and graphs of that data to provide a thorough understanding.

Color whisker plots in distance or coordinate mode, and deviation color scaling clearly show part position and tolerance conditions.

SmartFit 3D calculates the best position of a part for machining in its Tolerance Envelope Mini-Max optimization. Select SmartFit 3D results to output to Excel.

SmartFit® 3D is a fast, accurate, and reliable standalone 2D/3D best-fitting and analysis software package that compares CAD/nominal models to data from most measurement systems. SmartFit 3D is an interactive software environment where measured data is analyzed, optimized, and compared to CAD and theoretical data.

Sample Applications: SmartFit 3D at WorkSmart Fit 3D is ideal for best-fitting and analysis in virtually any manufacturing process

Analysis to aid propeller machiningUse SmartFit 3D to construct a profile tolerance for the blade that dictates its best position for machining. SmartFit 3D ensures there is material all around, and maximizes material in the places where it is most needed.

Next, let SmartFit 3D find the right position for machining the entire propeller, based on the blade tolerance profile, angular location of each blade in the assembly, and the pitch angle.

Turbine Blades and Propellers

Analysis of locator positions for machine die castingA dimensionally correct die may not always produce a dimensionally correct casting. A cast part may have areas outside the material or too much material in other places, causing rejection. SmartFit 3D can minimize guesswork and rework by optimizing the part against its CAD model.

Movements of die members, as well as other subassembly problems, are also easily solved by applying the “Group Release” function, which gives the values to be used in order to build the correct assembly.

Precision for People

• Eight mathematical criteria for best-fitting — Least Squares, Root Mean Square, Minimum Sum of Deviations, Mini-Max, Uniform Deviations, Minimum Standard Deviation, Tolerance Envelope, and Tolerance Envelope Mini-Max and Maximum Machining Allowance (Maximize the material for machining by direct optimization criterion)

• Calculation with uncertainty information — best fitting can take measurement uncertainties into account if provided. Optimization algorithms will achieve the best solution, with all uncertainty zones put into tolerance

• Tools for forcing a solution by weighting, excluding, or releasing points• Calculation of basic geometric elements certified by PTB• Cross sectioning capability — allows creation of cross sections from sophisticated freeform models, with analysis of errors

in 2D. Cross section can be included in reports or exported for further analysis.

• Multiple error display modes, including color mapping, statistics, graphics snapshots, and detailed point/error information• “Point to Point” and “Point to Surface” working modes• Built-in filters automatically invoked during measured data import• Annotations and basic dimensioning capability• Microsoft® Office™ 2007 color scheme• Reverse engineering, with 2.5D and 3D triangle mesh and conventional geometries from point clouds• Variable Tolerance Zone• Custom operations - allows creation of automated functional groups for immediate execution
